摘要
我们比较了具有不同工作恢复时间的低量高强度间歇训练(LV-HIIT)之间的生理和心理反应。10名成年男性按随机、平衡的顺序进行两次LV-HIIT训练。具体来说，60/60是LV-HIIT, 30/30是LV-HIIT。评估摄氧量(VO2)、二氧化碳排出量(VCO2)、通气量(VE)、呼吸交换比(RER)、感知用力(RPE)及影响。60/60 s LV-HIIT间期VO2(3.25±0.57 vs. 2.83±0.50 L/min)、VCO2(3.15±0.61 vs. 2.93±0.58 L/min)、VE(108.59±27.39 vs. 94.28±24.98 L/min)、RPE(15.9±1.5 vs. 13.9±1.5)较高(ps≤0.01)，而RER(0.98±0.05 vs. 1.03±0.03)和affect(-0.8±1.4 vs. 1.1±2.0)较低(ps≤0.007)。恢复期VO2(1.85±0.27 vs. 2.38±0.46 L/min)、VCO2(2.15±0.35 vs. 2.44±0.45 L/min)、impact(0.6±1.7 vs. 1.7±1.8)降低(ps≤0.02)，RER(1.20±0.05 vs. 1.03±0.05);p < 0.001)在60/60 s LV-HIIT中更高。较短的LV-HIIT (30 s)比较长的LV-HIIT (60 s)引起更低的生理反应和减弱的负面影响。
Physiological and Psychological Responses during Low-Volume High-Intensity Interval Training Sessions with Different Work-Recovery Durations.
We compared physiological and psychological responses between low-volume high-intensity interval training (LV-HIIT) sessions with different work-recovery durations. Ten adult males performed two LV-HIIT sessions in a randomized, counter-balanced order. Specifically, 60/60 s LV-HIIT and 30/30 s LV-HIIT. Oxygen uptake (VO2), carbon dioxide output (VCO2), ventilation (VE), respiratory exchange ratio (RER), perceived exertion (RPE), and affect were assessed. During intervals, the VO2 (3.25 ± 0.57 vs. 2.83 ± 0.50 L/min), VCO2 (3.15 ± 0.61 vs. 2.93 ± 0.58 L/min), VE (108.59 ± 27.39 vs. 94.28 ± 24.98 L/min), and RPE (15.9 ± 1.5 vs. 13.9 ± 1.5) were higher (ps ≤ 0.01), while RER (0.98 ± 0.05 vs. 1.03 ± 0.03) and affect (-0.8 ± 1.4 vs. 1.1 ± 2.0) were lower (ps ≤ 0.007) in the 60/60 s LV-HIIT. During recovery periods, VO2 (1.85 ± 0.27 vs. 2.38 ± 0.46 L/min), VCO2 (2.15 ± 0.35 vs. 2.44 ± 0.45 L/min), and affect (0.6 ± 1.7 vs. 1.7 ± 1.8) were lower (ps ≤ 0.02), while RER (1.20 ± 0.05 vs. 1.03 ± 0.05; p < 0.001) was higher in the 60/60 s LV-HIIT. Shorter LV-HIIT (30 s) elicits lower physiological response and attenuated negative affect than longer LV-HIIT (60 s).
